You can have your PIN reset at any of the card issuer's branches. Bring your credit card and at least two pieces of current identification to confirm that you are the card holder. If you're unsure if your identification is valid, call ahead and ask what you can use. A driver's license and a passport usually are good choices, since they both have photos. You may also have to answer questions about your address or transactions to help confirm your identity.
If you can't visit the bank in person, you can change your PIN number over the phone by calling the customer service number on the back of your credit card. Be prepared to answer questions about your address, provide your security password, and possibly answer questions about your credit card limit or balance to prove who you are. Calling the customer service line works if you've forgotten your PIN or mistyped it and are locked out of ATMs. Your bank will often reset the PIN remotely and give you a set amount of time to visit an ATM to select a new PIN.
ATM or Online
If your credit card was issued by a bank with offices and ATMs, a quick and convenient option is that bank's ATM. You'll need to know your current PIN to make the change. Enter your credit card and watch for an option about change the PIN or password. If you're registered for online banking, you also can request a new credit card PIN at your bank's website. Look for an option that lets you request a new credit card PIN.
Taking Care of Your PIN
Keep your PIN private. When you change your PIN, try not to pick a number that someone else could easily guess, like a birthday or street number for a house. Also avoid writing it down and storing it in your wallet with your credit card. If your wallet is lost or stolen, someone may find the PIN in your wallet or use your identification to figure out a pin. Change your PIN seasonally or every six months for extra security.
